' To` all/whom t may concern:

Be it known that we, FRANK X. LAUTER- BUR and PAUL LAUTERBUR, citizens o'f the United States, residing at Sidney, in the county, of Shelby and Stateof Uhio, have invented certainI new' and' useful' Improvements in Rotary Dough-Proofing Devices,

of which the following'is a specification.

The invention relates to a rotary doughproong device. The object of a simple practical and efficient cipally for use .in comparatively small baking establishments and adapted to save time and labor in the handling of the lumps of dough in proofing the same and equipped with a plurality of easil accessible dough receiving trays arrange at a convenient height for the workman and capable of being rapidly and successively filled and similarly emptied at the completion'of thcproofing process Without any unnecessary handling of the trays and Without requiring excessive stooping on the part of the workman.

lcapable and uninterruptedly performed without the delay of rearran ing a set of trays or receptacles to permit the'dough to be removed in the order-in which it was placed .in the trays or receptacles, as is the case in small bakeries. where a set` of loose trays or receptacles is employed and which are stacked one upon another as they are filled andrequire "a restacking 'or rearrangement in 'order to obtain access to the bottom tray or -receptacle which rst received .its contents.

llt is also an object of the invention to provide a dough'proofing device having a casinganda series of trays adapted to cooperate with the casing for completely cloS ing. the device to permit the dough torethe present invention is to'l l The frame 1s preferably made up .of tu main in a closed receptacle the necessary time to'complete thc dough proofing opera- 't1on, sald receptacles being adapted to be independently operated and instantlybrought to a position for exposing their contents.

Wlth these and other objects in View,

the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in .the

claims hereto appended; it being understood that various vchanges-in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

lin the accompanying drawings in which is illustrated the preferred embodiment of the invention, the rotary dough proofing device comprises in its construction a supof four vertical legs or nected at their upperv ends by dlametrically arranged ltop-cross b ars 2, cpntrally connected and supporting a depending Vern/Y tical pivot 3, on which are mounted 'a pl/urality of independently movable tra s lfi. u ar metal, such as ordinary gas pipe or the like, and the bars or pieces can be 'conveniently connected by the couplings 5 and 6. rllhe couplings 5 are l..shaped and connect the legs or standards with the top crossbars while the coupling 6 which 1s located porting frame or stand preferably composed,

standards il` conat the center of the top ofthe framefor stand, preferably consist of four horizontal arms and a central dependin arm to which the upper end of the centra pivot is conhowever be employed for connecting thel nected. Any other suitable means may or members of the supporting frame or Qi. the frame.

' legs or st of the top and bottom walls of the casing.

stand. The top and bottom walls 7 and 8 consist of disks having inward tapered approximately sector shaped cutaway portions or 'openings 12 and 13, the side edges of which preferably extendfromtwo adjacent andards to a point .near the centers The side wall consists of a portion@ of a cylinder having its vertical end edges 14.: located at two adjacent legspor standards and spaced apart substantially the distance betWceIl'the saine. By this construction a SllbStIltlally Cylindrical casing having an approxllnately sector shaped cutaway portion or opening is provided.

The trays 4 which are mounted for rotary movement on the vertical pivot-consist of a disk 0r plate forming the bottom lof the tray and provided with an inwardly ltapered cutaway portion or opening 15 and having a vertical marginal wall 16 extending entirelyI around the tray. The cutaway ortion 15 1s approximately sector shape or uadrant Shaped to conform generallyl to t e conguratlon of the openin in the top, bottom and Slde Wall of the cylindrical caslngand when the proofing device is closed thel trays are contained -within the casing and the cutaway portions of the trays are then arranged 111 register with the cutaway portion .of the casing. The marginal walls of the trays at the cutaway portions of the latter close the casing at the opening or cutaway portion of the same and access may be hadto` the contents 0f any one of the trays by rotating the Same on the vertical pivot 56 tobring different portions of such tray at the opening of the casing.

Any number of trays may be employed to provide-a .dough proofing device of the desired capacity and eachtray is provided at its periphery withA a horizontall pro- `jecting arcuate flange 17 located at t 'tomvof the tray and extending between up# per and lower anti-friction wheels or rollers 18 mounted in a suitable bracket 19 of approximately C-shape arranged at intervals and suitably secured to the side wall ofthe casing preferably at the legs or standards The anti-friction .rollers u.' support and maintain the-trays iii a horizontal position andl enable them to turn freely and preventsagging of the trays when e botlthe contents are unevenly distributed. The

anti-friction rollers may be mounted in various other Ways and they can be located at any suitable intervals to obtain the necessary support for the rotary trays In order to facilitate the ready adjustment or*nl rotary movement of the trays the latter are provided at opposite sides of the recesses or cutaway portions with suitable handles 20 secured 'to the exterior of the marginal walls and preferably in the form of loops but any other construction of handle may, of course, be employed. In rotating the trays the handle will enable them to be conveniently turned in either direction.

In Figs. 5 to 7 inclusive of the 4drawing is illustrated another form of rotary dough proofing device in which a central vertical pivot 21 is supported by a frame or stand aving legs 22 of a relatively wide spread to provide a broad supporting base and prevent accidental tipping or upsetting of the dough proofing device. The legs 22 which incline downwardly and outwardly are suitably connected at their upper endsf ,The vertical pivot which may be connected yat its lower end with the le s in anydesired' mannercoacts with the graine in supporting a casing 23 and has mounted on it rotary supporting members 24 consisting of diametrically arranged arms and secured to the lower faces of the bottoms of the trays 25. The casing 23 which is constructed i substantially the same manner as that i eretofore described is composed ofvtop, bottom and side walls and it has an inwardly tapered approximately sector orv quadrant shaped opening 26. The trays 25 are also of the same 4construction as those heretofore described with the exception of the omission of the projecting flange as they are suppprted by the diametrically arranged arms of the rotary frames or spiders 24 and do not require the brackets and anti-friction rollers. The rotary frames are provided with hubs 27 having upper and lower ball races 28 in which are arranged anti-friction balls 29 which lenable the vtrays to rotate freely' and frictionlessly. The up er and lower balls resist any tendency of t e trays to tilt or sag under an uneven distribution of their contents sothat the traysl in loading and unloading them will rotate without an binding action.
